High temperature pu pvc foam blowing agent yellow powder
Azodicarbonamide(AC or ADCA) is the most popular chemical blowing agent. Generally, AC is orange to pale yellow, crystalline solid with a decomposition temperature in air of 201~205ºC. Unlike a number of other chemical blowing agent, AC is self- extinguishing when flame is removed. The decomposition residues are odorless. non-toxic, non-coloring and non-straining. The particle size and distribution can be controlled with widely different ranges.The particle size and distribution is one of the significant factors.
